Lenze receives IEC 62443-4-1 certification: TUV Rheinland confirms cyber-secure development process
Lenze has been certified according to IEC 62443-4-1 since November 2025. TUV Rheinland thus confirms that Lenze meets the requirements of this internationally recognised standard for a secure development process for industrial automation and drive products.

The certification is an important milestone on the way to implementing the EU Cyber Resilience Act (CRA), which will become mandatory for machine manufacturers and their suppliers from December 2027.
The official handover of the certificate by TUV Rheinland took place on November 25, 2025 at the Lenze stand at the SPS trade fair in Nuremberg. Representatives from Lenze emphasised the importance of TUV Rheinland certification for the entire mechanical and plant engineering industry.
Cyber security as an integral part of product development
With the IEC 62443-4-1 certification, Lenze proves that security "by design" is consistently implemented throughout the entire product life cycle - from conception to development and maintenance. "The requirements for cyber security are increasing rapidly. Our customers can rest assured that Lenze products are developed to the highest security standards right from the start," emphasises Dr. Marc Wucherer, CEO of Lenze. "The certification is a strong signal to the market and a clear competitive advantage for our customers."
Structured processes for maximum safety
The IEC 62443-4-1 standard ensures that threat analyses, vulnerability management and patch strategies are systematically integrated into the development process. "With this certification, we are reducing the risk of cyber attacks and significantly increasing operational security for machine manufacturers and operators," explains Denis Gollner, cyber security expert at Lenze. "Our customers benefit from clear processes for security updates and a reliable security strategy over the entire life cycle of their systems."
Internationally recognised standard as a door opener
IEC 62443-4-1 certification is an internationally recognised seal of quality and a prerequisite for access to projects with high cyber security requirements. Many operators today demand that manufacturers in the supply chain have verifiably certified processes. With Lenze as a partner, machine builders meet these requirements and secure access to new markets," concludes Denis Gollner.
